Q1 : Whats this error ?

Q2 : Whats Best Way For Create Gallery Image ???

Answer 1

Q1: В нем говорится: java.lang.OutOfMemoryError: bitmap size exceeds VM budget
Это означает, что вы пытаетесь загрузить слишком большое изображение. Он не может храниться в памяти кучи VM.

Q2: См http://developer.android.com/training/displaying-bitmaps/load-bitmap.html

Answer 2

вашего размер изображения слишком низкая big.Use картина dimesion

Answer 3

Не загружайте 70 изображений за один раз, используйте lazy loading for loading images, а также использовать низкий размер изображения особенно .png изображений.

Answer 4

Моя библиотека ImageGallery очень проста в использовании. Это может быть то, что вам нужно.
